Species diversity structure analysis at two sites in the tropical rain forest of Sumatra

Data from a hilly forest study site at Batang Ule, Sumatra, are organized into 30 100-m × 10-m subplots lying perpendicular to the line of maximal topographic gradient, from the valley to the plateau/ridge. The following methodological question is addressed: what species diversity measures are best used in order to reveal the ecologically distinct regions in the site. The main tool used to answer this question is the α-diversity curve (Hα). Graphical examination of tree and species densities, and α-diversity curves identifies an anomalous species diversity behaviour of the ‘ridge above the slope’ subplots which may have implications on land-facet class definitions. Factor analysis of the α-diversity curves indicates that the diversity space is two-dimensional: i.e. two diversity measures are sufficient to characterize the site; the species density (H0), and the Berger-Parker index (H[infty infinity]). In the two-dimensional diversity-space three distinct species diversity groups are found which relate to the topographic gradient at the Batang Ule site. The results are compared with those for a flat homogeneous site at Pasirmayang, Sumatra. The implications of the results on land-classifications in species-diversity mapping and conservation strategy are discussed.

Longing and (un)belonging: desire and displacement in the cinematic city

This paper explores the spatial conceptualisation of the themes of diaspora, displacement and desire in cinema, particularly in the work of Nuri Bilge Ceylan (Uzak) , Fatih Akin (Gegen Die Wand) and Michael Winterbottom (Code 46). All three directors explore the imagined cinematic city as a site of multiple (un)belongings and interrogate how notions of identity are displaced and disrupted by geopolitics, by the city and by cinema itself. Both Ceylan and Akin’s visions of Istanbul are haunted by Beyoglu, both as the site of Istanbul’s contemporary cultural regeneration and by unspoken histories repressed by the Republic’s offical rhetoric of Turkish identity. In contrast Akin and Winterbottom’s heterotopias of the hotel and the hospital provide possible metaphors for these dislocated global identities. This paper will engage with a series of questions. What is the (imagined) place created between the viewer and the screen, or is it a non-place? Do the identities/ memories created there produce a ‘third space’? This paper uses Winnicot, Soja and Bhabha to ask what that third space might be and its consequences for a contemporary global Turkish identity. If these films depict a (Freudian) screen memory of dislocated subjectivities then what is being suppressed and sutured?

Polyunsaturated fatty acids in the pathogenesis and treatment of multiple sclerosis

Epidemiological, biochemical, animal model and clinical trial data described in this overview strongly suggest that polyunsaturated fatty acids, particularly n-6 fatty acids, have a role in the pathogenesis and treatment of multiple sclerosis (MS). Data presented provides further evidence for a disturbance in n-6 fatty acid metabolism in MS. Disturbance of n-6 fatty acid metabolism and dysregulation of cytokines are shown to be linked and a "proof of concept clinical trial" further supports such a hypothesis. In a randomised double-blind, placebo controlled trial of a high dose and low dose selected GLA (18:3n-6)-rich oil and placebo control, the high dose had a marked clinical effect in relapsing-remitting MS, significantly decreasing the relapse rate and the progression of disease. Laboratory findings paralleled clinical changes in the placebo group in that production of mononuclear cell pro-inflammatory cytokines (TNF-alpha, IL-1 beta) was increased and anti-inflammatory TGF-beta markedly decreased with loss of membrane n-6 fatty acids linoleic (18:2n-6) and arachidonic acids (20:4n-6). In contrast there were no such changes in the high dose group. The improvement in disability (Expanded Disability Status Scale) in the high dose suggests there maybe a beneficial effect on neuronal lipids and neural function in MS. Thus disturbed n-6 fatty acid metabolism in MS gives rise to loss of membrane long chain n-6 fatty acids and loss of the anti-inflammatory regulatory cytokine TGF-beta, particularly during the relapse phase, as well as loss of these important neural fatty acids for CNS structure and function and consequent long term neurological deficit in MS.
